Hinge Mounting Aid Using Clamping Screw and Adjusting Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting aids for hinges require large holes and additional components, leading to increased material and production costs, and are prone to misalignment and tilting during reinstallation, as they rely on single reference points that allow pivotability until additional screws are fixed, making precise and reproducible repositioning challenging.
Innovation Solution
A mounting aid using a clamping screw with an adjusting element that provides axial security through a tapped hole, eliminating the need for large holes and additional fastening means on the door arrangement part, and utilizing a mounting plate with a protective coating and adjustable disk design for secure and reproducible positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screw with a large hole is used for adjustment, then the hinge can be positioned and adjusted, but additional fastening means and threaded strips are required, increasing device complexity and manufacturing cost
Solution Approach 1:
The invention extracts the essential adjustment function from the complex screw-hole system and implements it through a simplified pin-in-hole mechanism. The pin (23) with adjusted diameter provides the adjustment capability without requiring additional threaded strips or complex fastening means, thereby reducing device complexity while maintaining ease of operation.
Solution Approach 2:
The pin (23) serves multiple functions: it acts as both the adjustment mechanism and the fastening element. By adjusting the pin's diameter to match the hole size, the same component provides both positional adjustment and secure fastening, eliminating the need for separate fastening components and reducing overall device complexity.
2Device complexity
If a single reference position is provided, then the structure is simple, but the hinge can pivot and tilt during reinstallation, reducing positioning precision
Solution Approach 1:
The invention segments the reference function into two distinct elements: the pin (23) that provides the primary reference position and the hole (27) that provides the secondary reference through its geometric constraints. This segmentation allows each element to contribute to positioning accuracy without creating a complex multi-component reference system.
Solution Approach 2:
The pin and hole are designed with asymmetric dimensional relationships where the pin diameter is specifically adjusted to be less than the hole diameter, creating a controlled clearance. This asymmetric design prevents pivoting and tilting during reinstallation while maintaining simplicity, as the clearance is intentionally designed rather than being a result of manufacturing tolerances.
3Adaptability or versatility
If large holes are provided for adjustment, then the hinge can be repositioned, but material removal and production costs increase
Solution Approach 1:
Instead of providing large holes throughout the door arrangement part, the invention applies local quality by creating a specifically sized hole (27) at the precise location where the pin (23) will be inserted. The hole dimensions are optimized for the pin's adjusted diameter, providing repositioning capability only where needed while minimizing overall material removal and production costs.

AI summary
The invention relates to an assembly aid for positioning a hinge (1) on a door arrangement part (12) in a reproducible manner, said assembly aid comprising a clamping screw (22) having a screw shank (23) and a screw head (21), and an adjusting element (20) which is applied to a part (17) of the hinge (1) in a positively locking manner. The adjusting element (20) radially engages with said screw shank (23) and can be axially fixed to the door arrangement part (12) by means of the clamping screw (22). The invention also relates to a method for the reproducible positioning of a hinge (1) on a door arrangement part (12) whereon a positioning axis (30) is provided. The aim of the invention is to provide an assembly aid and a method that enable a hinge to be precisely positioned in a simple and reproducible manner. To this end, the inventive assembly aid is embodied in such a way that there is radial play between the adjusting element (20) and the screw shank (23), and the screw head (21) engages with the adjusting element (20), or, according to the inventive method, an adjusting part (19) is arranged as a primary reference member at a distance from the positioning axis (30), and an adjusting element (20) is fixed in the position thereof as a secondary reference member with radial play in relation to the positioning axis (30).
